I accidentally removed some files from franklin's player one folder and now the character is strange , how can I fix
Grab the 'player_one' folder from the vanilla game folder:
...\Grand Theft Auto V\x64v.rpf\models\cdimages\streamedpeds_players.rpf\player_one
& drag & drop it out of OpenIV & then use it to replace the one in your 'mods' folder.
You can use Ctrl+F3 in OpenIV to search for files & folders by name. Very useful.
If you aren't using a 'mods' folder & deleted the vanilla files, you can use whatever verify integrity method is appropriate for your version of the game to get the files back:
